It provides power to the front wheels as needed to provide traction in slippery conditions and improved handling for a variety
of difficult road conditions.
If you need it, the four - wheel drive system is comparable to most trail - rated pickup trucks, allowing the Yukon to drive off - road or through
difficult road conditions with excellent traction and stability.
The Adaptive Dynamics package is standard as well, which features an adaptive suspension and a unique drive mode, which increases traction when you're
facing difficult road conditions.
The benefit, says Volvo, is greater capability on rough roads or in
difficult road conditions (regardless of the driven wheels).
